1 – IGLOO PLUS Device Family Overview
General Description
The IGLOO PLUS family of flash FPGAs, based on a 130 nm flash process, offers the lowest power
FPGA, a single-chip solution, small-footprint packages, reprogrammability, and an abundance of
advanced features.
The Flash*Freeze technology used in IGLOO PLUS devices enables entering and exiting an ultra-
low-power mode that consumes as little as 5 µW while retaining the design information, SRAM
content, registers, and I/O states. Flash*Freeze technology simplifies power management through
I/O and clock management with rapid recovery to operation mode.
The Low Power Active capability (static idle) allows for ultra-low-power consumption while the
IGLOO PLUS device is completely functional in the system. This allows the IGLOO PLUS device to
control system power management based on external inputs (e.g., scanning for keyboard stimulus)
while consuming minimal power.
Nonvolatile flash technology gives IGLOO PLUS devices the advantage of being a secure, low-
power, single-chip solution that is live at power-up (LAPU). IGLOO PLUS is reprogrammable and
offers time-to-market benefits at an ASIC-level unit cost.
These features enable designers to create high-density systems using existing ASIC or FPGA design
flows and tools.
IGLOO PLUS devices offer 1 kbit of on-chip, reprogrammable, nonvolatile FlashROM storage as well
as clock conditioning circuitry based on an integrated phase-locked loop (PLL). IGLOO PLUS devices
have up to 125 k system gates, supported with up to 36 kbits of true dual-port SRAM and up to 212
user I/Os. The AGLP030 devices have no PLL or RAM support.
Flash*Freeze Technology
The IGLOO PLUS device offers unique Flash*Freeze technology, allowing the device to enter and
exit ultra-low-power Flash*Freeze mode. IGLOO PLUS devices do not need additional components
to turn off I/Os or clocks while retaining the design information, SRAM content, registers, and I/O
states. Flash*Freeze technology is combined with in-system programmability, which enables users
to quickly and easily upgrade and update their designs in the final stages of manufacturing or in
the field. The ability of IGLOO PLUS V2 devices to support a wide range of core and I/O voltages
(1.2 V to 1.5 V) allows further reduction in power consumption, thus achieving the lowest total
system power.
During Flash*Freeze mode, each I/O can be set to the following configurations: hold previous state,
tristate, or set as HIGH or LOW.
The availability of low-power modes, combined with reprogrammability, a single-chip and single-
voltage solution, and availability of small-footprint, high-pin-count packages, make IGLOO PLUS
devices the best fit for portable electronics.
Flash Advantages
Low Power
IGLOO PLUS devices exhibit power characteristics similar to those of an ASIC, making them an ideal
choice for power-sensitive applications. IGLOO PLUS devices have only a very limited power-on
current surge and no high-current transition period, both of which occur on many FPGAs.
IGLOO PLUS devices also have low dynamic power consumption to further maximize power savings;
power is even further reduced by the use of a 1.2 V core voltage.
Low dynamic power consumption, combined with low static power consumption and Flash*Freeze
technology, gives the IGLOO PLUS device the lowest total system power offered by any FPGA.
